HAND-SETTlNG ATTACHMENT FOR TIME-PIECES.

SPECIFICATION forming part of Letters Patent No. 323,796, dated August 4, 1885.

(No model.)

To (1% whom, it may concern:

Be it known that 1, WM. E. DOOLITTLE, of New Haven, in the county of New Haven, and in the State of Connecticut, have invented certain new and useful Improvements in Hand- Setting Attachments for XVatches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,in which Figure 1 is a plan view of a watch containing my hand-setting mechanism a portion of the dial being broken away and said mechanism in position for moving the hands. Fig. 2 is a like view of the same, said mechanism being shown in dotted lines out of engagement Figs. 3 and 4. are plan views of the watch-movement separated from its case and with the dial removed, said handsetting mechanism being shown in'the respective positions occupied by it in Figs. 1 and 2; and Fig. 5 is a detail sectional view showing the construction of parts.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to enable handsetting mechanism to be easily and cheaply applied; to which end said invention consists,

principally, in the combination, in a watch, of the dial-wheels, a rotary disk or wheel journaled so that its edge projects beyond the edge of the dial, and intermediate gearing driven by such disk or wheel and adapted to be shifted into or out of gear with one of the dial-wheels without shifting of the disk, substantially as and for the purpose hereinafter specified.

It consists, further, in the combination, in a watch, of the dial-wheels, a rotary disk or wheel journaled below the dial, so that its edge projects beyond the dial-edge, but is hidden by the bezel when the latter is down or shut, intermediate gearing driven by the rotary disk or wheel and adapted to be shifted into or out of engagement with one of the dialwheels without shifting of the driving-disk, substantially as and for the purpose hereinafter described.

It consists, further, in the combination, in a watch, of the dial-Wheels, a rotary wheel or disk journaled below the dial, so that its edge projects beyond the dial-edge, the yoke pivoted on the same pin with the disk, the gear-wheel attached to the disk,and the pinion j ournaled on the yoke and adapted by the swinging of the yoke to be shifted into or out of meshwith one of the dial-wheels, substantially as and for the purpose hereinafter described.

It consists, further, in combining with the dial-wheels of a watch a pivoted yoke which carries a thumb-wheel and contains within a recess an intermediate wheel that is rotatable by the rotation of said thu nib-wheel, and may be caused to engage with one of said dialwheels by the oscillation of said yoke, substantiallly as and for the purpose hereinafter set 'ort It consists, finally, in a hand-setting attachment .for watches in which setting-wheels are held in engagement with the dial'wheels by means of a spring, and are removed from such engagement by the bezel when closed, substantially as and for the purpose hereinafter shown and described.

In the annexed drawings, A represents the top or pillar plate of a watch which has the usual dial-wheels, B and C, dial D, and minute and hour hands I) and c.

Pivot-ed upon a stud, a, which projects upward from the plate A, is a yoke, E,which has the form shown in Figs. 3 and 4., and at one end is provided with an arm, 6, that projects radially outward and furnishes a means whereby said yoke may be moved upon its pivotal bearing after the dial D is in position.

Journaled upon the stud a is a toothed wheel, F, which meshes with a like wheel, G, that is contained within a recess, 6, inthe yoke E. Said Wheel G has no pivotal bearing, but is held in place solely by the contact of its periphery with the sides of said recess and may be rotated freely therein by the movement of said wheel F, which movement is effected by means of a disk, H, that is secured upon the outer face of thelatter, and has such diameter as to cause its edge to project slightly beyond the edge of the dial D.

The side of the recess 0 adjacent to the dialwheel 0 is open, so as to permit the wheel G to be moved into engagement therewith by the oscillation of the yoke E, after which, by the rotation of the disk H, the dial-wheels B and C may be turned in either direction for the purpose of setting the hands.

The intern'lediatc wheel, G, is held in engagement with the dial-wheel O by means of a spring, I, which is secured to the plate A, and engages with the inner end of the yoke E, while said yokeis moved in an opposite direction, so as to disengage said wheels by means of the usual bezel, K, that, when closed, engages with the downwardcurved end of the arm e and forces the same inward.

As thus arranged it will be seen that by opening the bezel the hand-setting train is re leased so as to be throwninto engagement with the dial-wheels, and at the same time the projecting edge of the thumb-whcel or disk is uncovered for use, while by the closing of said bezel said hand-setting train is moved out of engagement with said dial-wheels and all of its parts concealed. Said attachment may be applied to any form of watch without injury to or mutilation of the same and at a trifling cost.

Having thus fully set forth the nature and merits olmy invention,what I claim as new is 1. In a watch, in combination with the dialwhcels, a rotary disk or wheel journaled so that its edge projects beyond the edge of the dial, and intermediate gearing driven by such disk or wheel and adapted to be shifted into or out of gear with one of the dial-wheels without shifting of the disk, substantially as and for the purpose described.

2. I11 a watch, in combination with the dialwheels, a rotary disk or wheel journaled below the dial, so that its edge projects beyond the dial'edge, but is hidden by the bezel when the latter is down or shut, intermediate gearing driven by the rotary disk or wheel and adapted to be shifted into or out of engagement with one of the dial-wheels without shifting of the (lllVlllg-(llSk, substantially as and for the purpose described.

In a watch, in combination with the dialwhcels, a rotary wheel or disk journaled below the dial, so that its edge projects beyond the dial-edge, the yoke pivoted on the same pin with the disk, the gear-wheel attached to the disk, and thepinion journaled on the yoke and adapted by the swinging of the yoke to be shifted into or out of mesh with one of the dialwhecls, substantially as and for the purpose described.

4. In combination with the dial-wheels of a watch, a pivoted yoke which carries a thu mbwheel and contains within a recess an intermediate wheel that is rotatable by the rotation of said thu1nb-wheel and may be caused to engage with one of said dial-wheels by the oscillation of said yoke, substantially as and for the purpose set forth.

5. A ha-ndsetting attachment for watches in which setting-wheels are held in engagement with the dial-wheels by means of aspring and are removed from such engagement by the bezel when closed, substantially as and for the purpose shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of June, 188i.

V. E. DOOLITTLE.
